This achievement is the worst.
I try to get into storm, by purpose, during night, and it would always be morning by the time I actually get into the storm or by the time I get out of it after getting in. The achievement is just excruciatingly tight in execution, you cannot get it accidentally you cannot get it by meaning it you can only get it accidentally by meaning to get it and you will just fail repeatedly for it.
Just remove the whole thing half of these broken trackers.
The cornrow being stuck to my orifice is also forcing this part of the event. You really wanted to make sure nobody gets it.
I will leave my original message above as it is. This WAS a thread venting my frustration with my situation that I finally found out to be caused of a bug or undocumented intended function of "Ashen Curse" vanity item, making your character count as a light (?) and thus halting you from getting the achievement and/or mission done if anyone in the crew has the curse equipped. I could not get much of verification to the effect of other other clothing or vanity options being able to cause the same thing, but for me and my friend, we had several failings after my initial frustration sessions. We just tested unequipping the curse (out of whim suggestion from my friend) and then succeeding in "Perfect Dark" registering.
The end result being, Ashen Curse, intended or not, will make Perfect Dark unattainable until unequipped.
